Question 243876: The unit of measure for a line is in inches. Use the distance formula to find the length of the line with points at (- 3, 0) and (4, 3). Answer by richwmiller(17219) (Show Source):
You can put this solution on YOUR website! c^2=a^2+b^2
is the formula for finding the hypotenuse of a right triangle.
Think of the points as the ends of the hypotenuse of a right triangle.
one leg (x) of the triangle goes from 4 to -3
so we subtract -3 from 4
and the other leg (y) goes from 3 to 0
so we subtract 0 from 3
so first we need to find the length of each leg of the triangle
where a=4-(-3)=7
and b=3-0=3
substitute
c^2=7^2+3^2
calculate squares
c^2=49+9
add
c^2=58
find square root
c=sqrt(58)= abt 7.6 inches
